MPQ7200GLE-AEC1-P

MPQ7200 is a high-frequency, constant current, buck-boost LED driver with integrated power MOSFETs. It offers a very compact solution to achieve up to 1.2A of continuous output current, with excellent load and line regulation across a wide input supply range. The MPQ7200 can also be configured for buck mode to provide up to 3A of constant load current. Constant frequency hysteretic control provides extremely fast transient response without loop compensation. The switching frequency can be fixed up to 2.3MHz in buck mode to reduce the current ripple and improve EMI. It can also be configured to as low as 1.15MHz for optimized efficiency and thermal performance in buck boost mode. The MPQ7200 requires a minimal number of readily available, standard external components and is available in a space-saving QFN-19 (3mmx4mm) package. Applications include turn indicator lights, daytime running lights (DRLs), fog lights and rear lights.
